Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority of U.S. Provisional Application 62/749,637, entitled “Product Dispenser Tips”, filed on Oct. 23, 2018, which is hereby incorporated by reference into this disclosure.

FIELD OF INVENTION

The invention relates generally to product dispenser tips and methods for use. Specifically, the invention discloses a dispenser having at least one product chamber in fluid communication with a product dispenser tip and method of using such dispensers.

BACKGROUND OF INVENTION

Disposable product dispensers (e.g., foil, plastic or plasticized paper dispensers) have been available for decades and provide convenient, disposable packaging for products such as condiments (e.g., ketchup, mustard, mayonnaise, soy sauce, and the like), soaps, conditioners, cosmetics, adhesives, paints, perfume, oils, and/or other substances.

In some dispensers, two layers of foil (or other material) are brought together and heat sealed or glued near the perimeter thereof along the various sides of the material. A suitable pre-perforation, or weaker material, is formed at or near a junction point between two sides of the condiment dispenser so as to permit easy cutting of this junction point away from the rest of the device. Thus, a user cuts along this portion removing a piece of material of the junction zone and proceeds to dispense the material from the cut area.

However, there are problems with this approach in that the current system can potentially be messy, leaving condiment material on the external surface of the dispenser. Also, the cutting or tearing of the junction may not be easy to perform.

Accordingly, there remains a need in the art for dispenser tips that more readily dispense material in a controlled and/or accurate manner, help maintain a clean surface of the dispenser, and permit the simple and easy opening of the dispenser.

SUMMARY OF THE INVENTION

The disclosed dispenser comprises a product chamber and an applicator tip.

The product chamber has at least two walls, with the first wall having at least a first side and the second wall having at least a second side. The walls are formed of an elastic material.

In operation, product chamber 101 is filled with a fluid or semi-fluid material, as seen in FIG. 1B. As a user applies pressure to the product chamber, inverted tip 201 may rupture at a perforation or other weakened area to permit the product within the product chamber to be dispensed.

Example 2

Dispenser

10 is formed of a product chamber 101 and applicator dispenser tip 210, as seen in FIG. 2A. Product chamber 101 is formed of any suitable material, that forms at least two walls, as described in Example 1. In an exemplary embodiment, the product chamber includes a first seal 151, along a longitudinal edge of first wall 110 and second wall 120, a second seal 152, along a transverse edge of first wall 110 and second wall 120, and a third seal 153, along a longitudinal edge of first wall 110 and second wall 120. The three seals, 151-153 for three walls of a single dispenser chamber 110, as seen in the Figure. Optionally, a fourth seal 154 is disposed on a second transverse edge.

Applicator dispenser tip

210 is in fluid communication with dispenser tube 215, having membrane 216 disposed in the interior of dispenser tube 215, as seen in FIG. 2B. Dispenser tube 215 traverses through fourth seal 154 (or a combination of seals on the transverse edge), and extends to the interior space of product chamber 101, thereby connecting the interior space of product chamber 101 with applicator dispenser tip 210.

In operation, product chamber 101 is filled with a fluid or semi-fluid material, as seen in FIG. 2C. As a user applies pressure to product chamber 101, the fluid or semi-fluid material builds pressure against membrane 216, until membrane 216 ruptures allowing fluid flow F₁to the applicator dispenser tip, as shown in FIG. 2D. Fluid flow F₁permits the product within the single product chamber dispenser to travel through dispenser tube 215 to applicator dispenser tip 210 to be dispensed or applied.

In certain variations of the invention, a second set of seals form an interior of the dispenser chamber, as discussed in Example 1. The interior seals seal three sides of product chamber 101, and include first interior seal 161, second interior seal 162, third interior seal 163, and fourth seal 166, disposed to permit dispenser tube 215 to extend to the interior space, as seen in FIG. 2E.

In some variations, liquid dispenser 10 includes a valve disposed in the interior of dispenser tube 215. While valve 217 can be disposed interior to membrane 216 or exterior to membrane 216, it is envisioned that in most variations, valve 217 is disposed exterior to membrane 216, thereby not contacting any fluid or semi-fluid until the rupture of membrane 216, as seen in FIG. 3 . Valve 217 is comprised of a spring or support 218 disposed in the interior of dispenser tube 215. Spring or support 218 is optionally integrally mounted to the interior of dispenser tube 215. Alternatively, spring or support 218 is supported by the interior of dispenser tube 215, via a lip, ledge, or ring integrally disposed on the interior of dispenser tube 215. Sealable membrane 219 is placed onto spring or support 218, and optionally sealed in place by a lip, ledge, or ring.

Example 3

Dispenser tube 215 traverses through fourth seal 154 (or a combination of seals on the transverse edge), and extends to the interior space of product chamber 101, thereby connecting the interior space of product chamber 101 with applicator dispenser tip 210. In some implementations, the applicator tips can fold over (and be secured with cellophane). In some implementations, the applicator can eject from the interior of the tip. Alternatively, applicator dispenser tip 310 is a folded applicator dispenser tip held in place by an adhesive film.

Example 4

Dispenser

10 includes product chamber 101 and brush applicator tip 410, as seen in FIG. 5A. Product chamber 101 is formed of any suitable material, that forms at least two walls, and includes at least a first set of seals, as described in Example 1. In an exemplary embodiment, the at least a first set of seals includes a first seal 151, along a longitudinal edge of first wall 110 and second wall 120, a second seal 152, along a first transverse edge of first wall 110 and second wall 120, a third seal 153, along a longitudinal edge of first wall 110 and second wall 120, and a fourth seal 154 disposed on a second transverse edge.

Brush applicator tip

410 is in fluid communication with brush dispenser tube 415. Optionally, brush dispenser tube 415 includes membrane 216 disposed in the interior of dispenser tube 415, as seen in FIG. 5B. Brush dispenser tube 415 traverses through fourth seal 154 (or a combination of seals on the transverse edge), and extends to the interior space of product chamber 101, thereby connecting the interior space of product chamber 101 with brush applicator tip 410.

In operation, product chamber 101 is filled with a fluid or semi-fluid material, as seen in FIG. 5C. As a user applies pressure to product chamber 101, the fluid or semi-fluid material builds pressure against membrane 216, until membrane 216 ruptures allowing fluid flow F₁to the applicator dispenser tip, as described in Example 2. Fluid flow F₁permits the product within the single product chamber dispenser to travel through brush dispenser tube 415 to brush applicator tip 410 to be dispensed or applied.

In certain variations of the invention, a second set of seals form an interior of the dispenser chamber, as discussed in Example 1. The interior seals seal three sides of product chamber 101, and include first interior seal 161, second interior seal 162, third interior seal 163, and fourth seal 166, disposed to permit dispenser tube 215 to extend to the interior space.

Example 5

Optionally, shaped dispenser tip 510 includes membrane 216 disposed in the interior of the dispenser tip, as discussed in previous Examples.

A fluid or semi-fluid material is added to product chamber 101. When pressure is applied to product chamber 101, the fluid or semi-fluid material is dispensed from shaped dispenser tip 510. Where a membrane is used, the pressure of the fluid or semi-fluid material ruptures the membrane, allowing the fluid or semi-fluid material to flow to the tip as flow F₂, seen in FIG. 6B. Optionally, a one-way flow valve is disposed in the tip.
